Specification of Letters Patent.

Patented Bec. 9, M119.

Application filed January l1, 1907. Serial No 351,802.

To all whom t may concern Bc it known that l. HUGH C.

MACC/0N- cation.

My invent-ion relates to certain improvements in machines for iiishing stereotype and other curved plates tor which Letters Patent were granted to me on the 31st day ot October. 1905, numbered 803,@2.

The obJect ot the present invention is to improve the details of construction, to make the. machine more automatic than heretotore, and to provide means for rei'iioving the plate after it has trimmed and iiished.

ln this machine the cuived for cooling and been plate is taken from the mold while still hot, placed on the saddle ci' the machine and pushed into position within the cy indi-ical shell. In its passage the longitudinal edges are trimmed and slightly beveled.

lilhen the plate is in position within the shell a lever is operated which will release the shell and automatically throw in the driving mechanism, the first movement of the shell releases a clamp plate in which holds the the shell, and as the shell with the plate is rotated the ends of the plate are beveled and the gate detached.

The inner ribs of the plate are also trimmed as the cylinder and plate rotate around a fixed knife. lVhile in the machine water is preferably sprayed upon the so as to cool it.

plate lf-.lhen the cylinder reaches a certain point the discharge mechanism is automatically thrown into action and the plate is removed from the cylindrical shell and transferred onto a roller bed which conveys it into a cooling box which is. supplied with spray pipes for again spraying the plate.

After the plate is cooled from the opposite end ot' the said box.

it is removed The above description will give a preliminary idea o the operation oi the machine.

The machine is particularly adapted tor trimming and finishing stereotype plates used for printing newspapers and periodicals, although it will be understood that it can be used for trimming a curvedV for any purpose.

plate of the shell so as In the accompanying d 'awingsz- Figure 1, is a longitudinal sectional view ot' my improved machine 'for inishing stereotype and other curved plates;

Fig. 10, is a view of a mcdiiication of the plate discharge mechanism; and

Figs. 11 and 12, are views ot the curved plate with the gate attached.

A is the frame of the machine supported upon a flanged bed plate A', this bed is flanged in order to catch any drip 'from the machine. Y

A2 is a fixed saddle projecting in front of the machine and secured to the traine in any suitable manner. From Fig. 1, it will he noted that the -forward part or' the saddle is depressed, while from Fig. 2l it will be seen that the sides of thatk portion of the saddle immediately in front of the. slot h hereafter referred to, are recessed; this provision ot' a depressed portion and recess or recesses being for the accommodation ot' the ,projecting lug usually formed by the gate on the inside of stereotype plates.

B is a cylindrical shell having` annular grooves at each end in the present instance. The shell rests upon transversebearings a., a forming part oitthe frame A, the bearings extend into the grooves of the shell, as shown clearly in Fig. 1, and caps a are secured to the frame A and alined with the bearings a, a and also vrest in the groove o to firmly hold the shell against longitudinal, movement, but allowing it to freely rotate when motion is imparted to it. rlhis arrangement makes a very steady support for theshell as a neat it can be made between the bearings and the shell.

@n the central portion of the shell is an annular rack b which meshes with the teeth ot a worin wheel c on a transverse shalt C. This shaft is adapted to bearings o, c se` cured to the trame A, as clearly illustrated in F ig. 1l, and has at one end a gear w ieel c2 which meshes with a pinion cZ on the shaft ot the n'iotor l). This motor in the pres ent instance is mounted on a bracket D secured to the traine A. rlhe motor may be of any suitable type and while have shown an electric motor any means may be used for driving the mechanism without depart-ingl from the essential features of the invention.

E a lixed longitudinal bar mounted in bearings a2 on the rramc and is held troni turning by ineans oit set screws or other snitable tastenings.

E is a knife carrier secured by screws e to the shalt E; e is a knife blade which can be adjusted on the carrier by means of set screws e2. lhe blade e trims the internal ribs ad, Figs. ll and l2 of the curved plate, and is held in a tixedrposition while the plate is carried past it.

. F a cutter shaft on which are iiiountec the cutters f, which bevel the ends 02, 03?' of the plate, and the cutter also detaches the gate ai from the body :e of the plate as the plate is rotated past the cutters.

rllhe shalit F is driven by bevel gearing fl, f3 :from a transverse shaft F mounted in suitable bearings f1 on the traine A ot the machine. This shalt F is driven by a belt (Z2 directly from the armature shaft ol the motor, as clearly indicated in Figs. 23 and sl. The belt shown a toothed metallic belt engaging the sprocket wheels Z3 and j on the shaits d and F, respectively.

C- is a transverse sli-att mounted in bean ings g on the front end of the `trame A, F 2b, and on this shaft are cutters 5/ which are so set in respect to the flanges a3 oi the saddle A2 that when the plate travels on th -se llanges to enter the machine the cutters r, g trim and slightly bevel the longitndinal edges ft2, :c2 ot the plate, Fig. 5.

The shaft G is driven by a belt g2 from the shaft F. as clearly illustrated in Figs. 2 and 2b.

lt will be noticed in referring to Fig. 2b, that the liange a3 is notched in front ot the cutters g, g so as to allow any shavings or chips which may accun'iulate on the flange to be pushed aside so that the plate will seat itself correctly on the flanges.

llhe saddle A2 is preferably made in the peculiar shape shown in Figs. l and 2b so that the operator can have plenty of room to adjust the plate on the wide iianges ot the saddle; and at the rear end of the saddle is a longitudinal slot ,li which connects with.

vdown the lever the arms 2'.

a transverse slot t, these slots act as a guide and also as a stop to limit the inward movement ot the plate when introduced into the machine, as l cast, on the gate end ai of the plate a lug (e6, F ig. l2, which alines with the slot 7L and when the plate is pushed into position within the cylindrical shell the lug enters the slot t and comes to 'a stop against the wall if directly in line with the transverse slot It. rhis arrangement seats each plate proper-.l i in position so that the knives j which trim the ends of the plate will take the proper amount ot material olf the plates at the proper point.

is the plate revolves with the cylindrical shell the lng af travels in. the slot a and when the gate, which is accommodated in the recesses in the side of the saddle is sew ered by the cutter 'the plate is freed from the control ot the said slot and is in position to be moved ont or the shell after it has been trimmed by the several cutters. rlhe gate m falls onto the inclined portion fr* of the traine and slides to one side ot the machine.

lt will be noticed in the drawings that the saddle A2 extends only to the front end ot' the shell and the ilanges t3 of the saddle aline with internal ribs b2, 3 in the shell. These ribs preferably extend the full length of the shell and carry the plate, the rib lf pushes the plate past the cutters until the plate again comes to the position ot' rest, as indicated in Fig. 3, of the drawings.

lt will be noticed in Fig. G, the internal rib Z22 is held in place by a spring 6G; and on the roar of the rib is a beveled portion Zr" which bears against a wedge bs, this wedge is forced in by a arin b secnrei to the traine A, so that when the cylinder is in position to receive the plate the rib is depressed so as to allow sutlieicnt clearance for the plate to be inserted in the cylinder, but as soon as the cylinder commences to rotate the wedge bs passes the arni 21? so that the spring 6G will in'in'iediately torce the rib against the plate and lock the plato rigidly to the shell.

On the shaft C is a clutch sleeve l, hav` ing teeth arranged to engage teeth on the hub ot the worin c, a spring e' tends to keep the clutch in engagement.

l is a yoke which carries two arnis v" with wl V`ch engage lugs 714 on the shell ll, as indicated in Fig. Ll. lThese arms are pix oted to trunnions on the clutch l.

l2 is a lever pivoted at is and attached to the yoke l as indicated so that on pressing will be raised clear of the lug ZJ, allowing the clutch teeth to be thrown into mesh with the teeth ot the worin by the spring i.

lt will `be noticed that there are stops '/1L i'ixed to the traine orn the machine which limit the rearward increment ot' the, clutch lill) I. By this arrangement the cylindrical shell is brought to a stop at a certain point by the lugs ZI* coming in Contact with the arms 2. In order to allovv a certain amount of yield the spring z' Will cushion the arms z" and as the cylindrical shell is rotated it will force the clutch out and When the clutch is disengaged from the teeth on the Worin vrheel the Worm wheel Will stop and consequently the Worm ivill lock the cylinder in Yposition and the cylinder in turn Will .pre-

vent the clutch being forced into engagement with theteeth on the Worin Wheel until the arms z" are raised by the leve-r I2 when it is desired to cut another plate.

At the rear end of the machine is a roller table J having a series of rollers which have roughened surfaces y" at' each end upon which the edges of the plate rest when it is carried out of the shell. These rollers are driven by a chain jg Which engages a sprocket lwheel on the ends of the rollers, the rollers being driven from the transverse shaft F through an inclined shaft J. There is asivorm y'3 on the shaft F which meshes with the Worm Wheel j* on the shaft J', and this shaft in turn has a bevel Wheel Which meshes with' a. bevel Wheel j on one of the rollers y', as indica-ted clearly in Figs. l and 2a. t

The table is continued inside of a spray box K as clearly indicated in Figs. l and 2 and the rollers T are driven by a chain i3. The first roller in the box is driven by a chain jf vvhioh passes around a. sprocket Wheel on this roller,- and on the roller upon which the bevel Wheel y'G is mounted.

The spray box is closed at both ends and has curved slot-s ZJ, Z3 through which the curved plate is passed. rIhis arrangement contines the spray Water to the box. Pieces of felt or other material may be arranged to form valves to close these openings if desired.

L is an endless chain which extends through the shells B, passing around sprocket ivheels Z, Z at each end, one of the Wheels is driven by a chain Z which passes around a Wheel Z2 on one of the transverse rollers y'. Engaging the toothed hub of this Wheel is a clutch Z3 actuated by a rod Z4E extending through. the center o f the roller and this rod is actuated by anA arm m on the longitudinal shaft M which has an arm m in the path of the lug b5 on the cylindrical shell B, as indicated in Fig. 6. l y

On the chain Il is a lugrZ5 Which engages the rear end of the-plate and pushes it out of the shell When t-he plate is iinished, onto the rollers To throw the driving mechanism for the chain L out of gear I provide the shaft M with an arm s which ext-ends under another arm s in the path of the.

plate, as indicated clearly in Figs. 2a and 7.

so that when they, plate comes-.in ,Contact with this arm it depresses it and throws the clutch out of gear.` IThe lug b5 throws the will be impossible for the chain to accidentally remove the plate before it is iinished and before it is in position to be removed, as it Will be understood that While the plate is being cut it is held rigidly in the shell.

N is a seriesof Water spray pipes mounted Within the shell B, and P is a series of Water spray pipes mounted Within the'casing K. rIhe Water spray pipes N are connected to a pipe N in Which is a valve a actuated by cams n on the shell B so that when the shell reaches a certain point t-he Water vvill be turned on and a fine spray of Water Will be played upon the plate by the several spray pipes, gradually and partially cooling it WhileV in the cylindrical shell. The 4moment the rotation of the shell is stopped the Water is cut oft' and the plate is removed by the endless chain and conveyed into spray boxes K.

As the plate enters the spray box it trips a lever p of the valve p in the Water pipe IJ and the Water passes through the several spray pipes and plays upon the plate ivhile in the box. As the Aplate is removed from the box it actuates a lever p2 connected 4to the lever .10 by a rod p3 which turns the valve to cut off the Water so that unnecessary Waste of Water is avoided.

In some instances in place of the endless chain for removing the plate from the shell, a double threaded scr-civ L may be used driven by a train of gears from the shaft F. L2 is a reciprocating carrier actuated by the screw and having a trip pavvl which Will engage the plate and push it out of the shell but when returning vvill fall back to pass a plate which may be in the shell and spring up back of theplate to be in position to push yit forward at the nextfoig Ward movement. This is clearly shovvn in Fig. IO.

Under operating conditions a plate, usually immediately after it has been cast and While it is still hot, is placed upon the saddle A2 and pushed into the shell until the lug m6 cast Aon the plate enters the slot Zt and comes to restagainst the .vall 71,2 thereofin line with the transverse slot ZL. I n Ybeing pushed over the saddle the longitudinal edges 002 ofthe plate are trimmed and .slightly beveled by the cutter f/ and after -vsaid plate comes to rest Within the shell, the latter' is operatively connected Ito lthe motor so as to be caused to revolve,

by pressing down the lever I2. This permits the teeth of the clutch I, under the A.action of the spring t', toenter thecorrespending teeth formed on the Worm so that this latter is turned and with it the shell.

Immediately upon the beginning of this revolution, the Wedge o8 moves out of engagement with the arm of so that the spring forces the rib 52 against one edg'e of the plate .and rigidly locks this in the shell.

Shortly after the revolution of the shell begins, the cam n acting upon the valve in the pipe N causes Water to be admitted to said pipe so that a line spray is played upon the plate, which is thus gradually, though only partially.I cooled While in the shell. rllhis flow of Water is cut off by the action of the cam on the valve shortly before the shell finishes its revolution.

After the plate has turned through an are of almost 1800, its. advancing edge comes into engagement; with the cutters j and so that the gate portion is severed from one of its ends and its opposite end is trimmed to the desired form.

It Will be noted that the cutters, and particularly the cutter f, is so placed ythat it finishes its Work of severing the gate portion of the plate only after this latter has almost reached its original position ,Hthat is, When it is in such a position that the gate portion is largely carried by the saddle.

l/Vhile I preferably mount the cutter as noted, it is to be understood that it may be placed in other positions to accomplish the same and Without departing from my inventiom-the object to be attained being the prevention of a premature separation of the gate portion from the body of the plate owing to the former breaking away before the cutter f has finished its Work.

After the advancing edge of the plate has passed the cutters f and 7, the interior surface of the same is engaged by the knife e and is shaved or trimmed in the desired manner ,-it being noted that said knife is so placed as to finish its Work on the plate just before this latter has completed its revelution and comes to rest owing to the lugs contacting with the arms @"and throwing the clutch I out of action.

Immediately before the shell has linished its rotation, the arm b9 acts to release the rib b2, so that the plate is released, and immediately thereafter the lug 55 causes the clutch Z3 to connect the endless chain L with the source of power, so that the lug Z5 on said chain engages the rear end of the plate and pushes it out of the shell and on to thc roller table J. This latter carries the trimmed plate into the spray box K and in entering this it trips a lever 7) so that the valve p is operated, and Water is delivered to the spray pipes I), thus causing the plate to be completely cooled to any temperature desired, depending upon the amount of Water delivered by said pipes, Which may be regulated as desired.

As the plate leaves the spray box it turns oft the valve p through the levers p and p2.
